CEMENTING- MACHINE.

Application filed April 27, 1922. Serial No. 556,870.

This invention relates to cementing machines, and more particularly concerns apparatus for applying adhesive to the tops of tennis or like rubber-sole shoes. These tops are sometimes formed with the'edges about the toe-portions scalloped, so that in lasting these over the insoles, they will lie more smoothly, due to the absence of protuberances in the gathered-in material In cementing such tops for their attachment to the insoles, it is desired that over the scalloped portion the work shall be coated to the full depth of the projections and over some or" the adiacent material inside their bases, and that beyond these scallops the edge shall receive a band of the adhesive of less width. This operation presents diliiculties, because the projections from the body ot' the material are easily displaced or twistedgleading to their being' cemented together in this position, in which they do not properly extend over the insole in lasting. Then, too, the applying; member operating over the projections also acts between them, and tends to deposit cement upon the co-operatinr; pressure or work-supporting member. The lastmentioned effect is further produced during the operation upon the narrower area at each side of the scallops. This daubing' of the pressure member piles cement up at thebases or the scallops, causing objectionably uneven coating.

My invention has as an object the provision of a machine .oy which work having the above-described or similar characteristics may be coated uniformly and without distortion. In the attainment of this object, a coating member and the work are held. in applyin relation with less pressure over the projcc ns than over the body of said work. In carrying out this operation, I preferably combine with a rotatable cement-applying men'iber a rotatable work-engaging pressure member and an associated worloengaging member lined relatively to the rotatable member and separated from the applying member by a greater distance than is said rotatable member. This arrangemen. permits a positive advance of the work by the firm contact of the applying member and rotatable pressure member with it, especially over the continuous portion, while the companion engagin member may touch the projections of the scallops so lightly that they will not be displaced, though held closely enough to the applying member to receive their coating. Moreover, the extent of separation between the applying member and this iixed member prevents the latter from gathering cement and delivering it irregularly to the work. Prel erably, both ;-he applynig' member and rotatable work-em 'ng member, the latter supporting the pork in the present embodiment of the invention, are in the form of rolls driven to advance the work, while the assoc ed work-engaging and supporting memb i. may consist of a rigid linger,-which, once properly related to the work. will perform its functions untailingly and without attention.

Another object of the invention is to tacilitate the correct presentation of the work to the applying member by the operator. For this purpose, there is associated with the applying member and the plural pressure members a gage, having means for guiding the work in contact with both pressure members and means arranged to guide said work in contact with but one of the pressure members. In the first instance, the full width, including the projections and the adjacent bod of the material. may be coated, while in the second, the J ower band at eacli side of the scallops may be applied. This gage is shown as extending: in front of tee applyin n d prrssure meu'ibers, with respect to thc ntation ot the work thereto. and pro vided with substantially vertical worlrguiding surfaces separated transversely of the direction of feed.

The improved method of treating flexible sheet material disclosed herein is claimed in my conch-ding application Serial No; 178,435. filed March 25. 1927, which is a division of the present application.

In the accompanying drawings, illustrata particular embodiment of the invention.

Generally, the apparatus may be as dis closed in the patent in my name No. 1,380,360, dated June 7, 1921. This has, supported upon a frame 10, a receptacle 12 for delivering cement or other adhesive to an applying roll 14. The applying surface of this roll may have projections 16 extending in series both circumferentially and laterally of the roll, between which projections are intermediate spaces, serving as pockets to hold the cement which is laid by the points of the pro jections upon the surface to be coated. The width of this surface is such as to make the application of cement to the maximum width of the area to be coated. A piece of the work is indicated at T in Fig. 4 of the drawings, this being the toe-portion of the top of a tennis shoe. About it are projections a, between which are curved depressions b forming a series of scallops, which gradually decrease in depth from points near the forward extremity of the toe to those at each side. The full height of these scallops is to be coated, and also a band at 0 within their bases, this band, beyond the toe-portion, extending at each side of the top at (Z and being narrower than the width of the coating applied to the sealloped portion. I

The applying roll 14 is fixed upon the outer end of a shaft 18'rotatable in the frame and driven from a suitable source of power. Pivoted upon the frame, below the shaft 18, is an arm 20, in which is rotatably mounted a shaft 22 also driven and having secured to it, beneath the roll 14, a pressure and worksupporting roll 24. The arm with the shaft and roll may be raised to bring the latter into co pera'tion with the applying roll by treadle or spring mechanism (not illustrated), the upward movement being limited by a stop screw 25 carried by the arm and contacting with the overhanging portion of the frame. As here shown, the roll 24 is arranged with its outer edge outside the cone spending edge of the applying roll 14, and it extends beneath said roll to an amount at least substantially equal to the width of the coated area (Z upon the work. Adjacent to the roll 24, at its inner side, is an associated pressure and work-supporting member, preferably consisting of a finger 28, which may be of cast metal or other rigid material, this finger having a supporting shank 29, from which it curves upwardly and rearwardly substantially concentric to the periphery of the roll 24. Its width is at least a substantial portion of the maximum depth of the seallops. In the present embodiment of the in vention, this finger is mounted upon a block 30, which also furnishes awork-gage and which is carried by the arm 20. To this it is secured by a screw 32 passing through a horizontal slot 34 in the block and threaded into the arm. By this mounting the gage-block may be varied in its position with relation to the applying roll to change the width of the area to be coated. To the rear of the block the shank 29 of'the finger is fixed by screws 36, 36 passing through slots 88 in the shank and engaging the block. This slot-and-screw connection furnishes an adjustment for the finger toward and from the applying roll; but'once the correct position is determined, this may remain unchanged. The proper location for the finger in the performance of the work for which this apparatus is particularly designed is just below the adjacent periphery of the roll 24, so that the cement carried by the applying roll 14 will at all imes be out of contact with the finger, and the work between the finger and applying roll will be subjected to less pressure than that portion between said applying roll and the supporting roll 24. Upon the block 30 are two substantially vertical work-guiding surfaces 40 and 42, the former being shown nearly in vertical alinement with the inner edge of the applying surface of the roll 14, while the surface 42, which is at the outer end of the block, is shown adjacent to the side of the roll 24. The distance between the guiding surface 40 and the outer edge of the applying roll corresponds to the maximum width of the area to be coated, including the projections and the band 0 within them. When the surface 42 is employed as a guide, thev space coated is that indicated at d.

In using the machine, the operator may start at the heel-portion of the top, and employing the surface 42 as a gage, moving the outer edge of the work against this or in vertical alinement with it, may advance the end of the work between the rolls 14 and 24, which, in their rotation, feed it forward, the former applying to it a coating of cement fromthe receptacle 12 to cover the area cl. in this connection, the finger 28 is inactive, being beyond the edge of the work, but is sufficiently removed from the cement-laden surface of the roll 14 so that it is not daubed by it. As the scalloped, portion at the tee is approached, the operator shifts the work laterally between the rolls until its edge is directed by the surface 40. At this time. both the roll 24 and the linger 28 are effective to maintain the material. in engagement witl the applying roll, the projections of the seallops being held with so little pressure against said roll that they are not displaced, and the separation between the roll and finger keeping the latter clean during the passage of the depressions Z). Having rounded the toe-portion, the work is again. moved laterally to utilize the surface 42 as aguide and complete the coating of the narrower area (Z at the 0pposite side. i V
